📫 Business - jawadrana2015@gmail.com In a Node.js project, the scripts field in the package.json file allows you to define custom scripts that can be executed using npm. These scripts are often used for various development tasks, such as running tests, starting the application, building the project, or performing other custom actions. Here's an overview of how scripts work in the package.json file: Syntax: The scripts field is an object where each key represents the name of the script, and the corresponding value is the command or script to be executed. The syntax looks like this: json Copy code "scripts": { "script-name": "command-to-run" } For example: json Copy code "scripts": { "start": "node index.js", "test": "jest" } Default Scripts: npm provides a few default scripts that can be executed using npm run script-name. These default scripts include start, test, stop, restart, and others. For example: npm start: Executes the start script. npm test: Executes the test script. npm stop: Executes the stop script (if defined). Custom Scripts: You can define custom scripts to automate tasks related to your project. These scripts can be named anything you like and can execute any valid command or series of commands. For example: json Copy code "scripts": { "build": "webpack --config webpack.config.js", "lint": "eslint .", "deploy": "npm run build && rsync -avz dist/ user@server:/path/to/destination" } In this example: The build script runs webpack to build the project based on a configuration file. The lint script runs ESLint to check code for linting errors. The deploy script first builds the project using npm run build and then deploys the built files to a server using rsync. Running Scripts: To run a script defined in the package.json file, you use the npm run command followed by the script name. For example: sh Copy code npm run build This command executes the build script defined in the scripts field. Environment Variables: You can also use environment variables within scripts. For example, to pass an environment variable to a script: json Copy code "scripts": { "start": "NODE_ENV=production node index.js" } This script sets the NODE_ENV environment variable to production before running node index.js. By using the scripts field in the package.json file, you can automate various development tasks and create a consistent workflow for managing your Node.js project. #nodejs #javascript #coding #node #backend #nodejstutorial #nodejsdevelopment #tutorial #tutorials #programming #nodeprogramming #npm 0:00 Introduction 0:29 Practical 3:14 Example
